Reduced Pressure Differential Hydroelectric Turbine System

ABSTRACT

This invention involves a hydroelectric turbine system that is capable of producing electricity while sustaining a majority of the fluid flow or hydraulic pressure within the pipe line or pipe network driving the system. The system&#39;s objective is to shave as little pressure as possible from an enclosed pipe system that requires pressure to operate and function properly. More particularly, this invention relates to a hydroelectric turbine generator system wherein the system is specially designed and configured with an unique impeller and fluted turbine housing that enable a generator device to produce a particular amount of electric current and voltage, while yet minimizing flow restriction and pressure loss to the fluid pressure driving the system. Application of this technology includes all fluid flow or fluid transfer systems that require sustained pressure to move fluids like water or other materials from one location or point to another, through pipes, pipe systems or networks, regardless of distance or pipe size diameters. This invention, for example will be ideally suited for powering electronic control or monitoring systems in landscapes, parks, roadway easements, golf courses or public water transfer systems or other remote sites that may require power. Utilization of this invention provides an ecological and reliable energy production source, usually on a small scale, in remote locations where incorporating other forms of power supply may be less practical, impractical or impossible.

FIELD OF THE INVENTION

This invention relates to a hybrid hydroelectric turbine system for producing electric power. More particularly, this invention relates to a hybrid hydroelectric turbine generator device for producing electric power; wherein, the turbine's impeller and flute housing are specifically designed, for maximum efficiency, so as to produce an electric current and voltage, while yet minimizing fluid flow restriction and pressure loss to the hydraulic delivery system and/or the fluid flow pipe line supply source. The design objective of this invention is characterized as minimizing the pressure differential between the system's inlet and outlet sections and wherein sustaining downstream hydraulic pressure is as critical and equally important to producing electric energy.

BACKGROUND OF THE INVENTION

Various turbine-generator designs have been utilized to produce electric power for many years and are well documented. A typical turbine generator system is an electrical generator device that converts kinetic energy derived from a fluid flowing under pressure to electrical energy usually using electromagnetic induction. Though there are a multitude of different designs that describe various types of hydroelectric turbine systems that serve different applications, they all share a single objective. That is, they seek to produce as much electric energy as possible utilizing as much available hydraulic flow and pressure as possible. Maximum efficiency is characterized, in these designs, by achieving high levels of electrical production using all available fluid flow and particularly pressure from a supply source. None, if any, considers the condition of the fluid material once it has left the surface of the final blade or impeller vane that serves to drive a generator shaft.

A traditional turbine-generator system consists of a turbine impeller, impeller housing, and a generator or alternator device which are coupled via a shaft. The turbine is used to convert momentum from a fluid stream into rotary motion. The shaft transmits the motion to the generator rotor, which typically contains permanent magnets or coil windings around each of its poles. Power is generated by flow under pressure that comes into contact with an impeller or a multiple blade type device that turns a common shaft.

There are different types of impeller designs and are generally considered reaction, cross flow or impulse types. They develop kinetic energy by the drive force supplied by a concentrated stream or jet of fluid which is deflected off cups or paddles tangentially or axially across an impeller such as in a Pelton, Turgo, Banki, Kaplan or Francis turbine designs. The water's potential energy is converted to kinetic energy with a nozzle or restrictive orifice in some cases. The high speed water jet is then directed onto the turbine blades which deflect or reverse the flow such as is characteristic of the popular Turgo turbine design. The Francis turbine is also a common design used in many large applications such as dams and flowing rivers where piping is used to convey water down flumes to develop head pressure that drives this reaction type turbine, which means that the working fluid changes pressure as it moves through the turbine, surrendering its energy. A casement or housing is needed to contain the water source or intake flow and is called an inlet scroll. The impeller is located between the high pressure fluid supply source and the low pressure water exit located just after the impeller.

The Francis Turbine's volute or inlet scroll is spiral shaped. Guide vanes direct the water tangentially to the runner. This radial flow acts on the runner vanes, causing the runner to spin. The guide vanes or wicket gate may be adjustable to allow efficient turbine operation for a range of water flow conditions. The impeller is an inward flow design and moves the fluid through the runner as its spinning radius decreases, further acting on the secondary runner blades or vanes.

Virtually, all hydroelectric turbine generator designs share a common objective of producing as much electric energy as possible and prefer maximum flow under high pressure to achieve that goal. Efficient designs are built upon the premise of extracting as much energy as possible from the fluid flow under pressure driving the system and are not, typically, concerned with the state of the flow once it has been discharged from the impeller. That is, the primary objective is energy production and not sustained downstream pressure. Such designs achieve higher flow velocity by increasing head pressure using several means and equate efficiency to the design if it uses all available pressure to produce electricity. A common turbine design modifies inlet flow by attempting to concentrate it prior to its contact with the impeller. This is accomplished by the use of nozzles or channeling flow down into a smaller orifice, chamber or pipe size diameter like a flute type structure to increase the flows pressure right before it contacts the turbine. Such restriction increases flow velocity or speed across the impeller's veins or blades and turns the generator faster to produce more power, but subsequently sacrifices downstream pressure in the process.

However, there are numerous other uses or applications that would benefit substantially from hydroelectric turbine power if it could be utilized, but can not at this time because of the restrictive nature or pressure differential characteristics. A product has not been developed, to this point that specifically addresses the needs of such applications or markets where electricity is use to power various electronic devices.

Fluid flow conveyance systems like piped irrigation or large volume water, oil or gas transfer and especially ones that are remotely located or difficult to access with conventional power are best managed using processor driven control systems that incorporate sensor input and communication capability. Applicable electronic control technologies that enable various levels of monitoring and management control of remotely located pipe lines require electricity. Such systems are usually supplied by metered utility power, wind or solar power which can be difficult to impossible or impractical to implement. Therefore, furnishing power to electronic control and/or communication systems, lighting etc. using energy derived from the same pipe lines the system is managing, or in close proximity to, would provide an ideal power alternative.

Solar and wind electrical generation are good renewable energy alternative sources but have several disadvantages. From an aesthetic stand point they are not attractive for urban and suburban use and can be susceptible to vandalism because of the high profile installation requirements of both systems. Both require that they be placed sufficiently high above grade level in order to effectively capture and produce energy, which make them a good target for vandals. Furthermore, in remote locations like rural environments, they are even more susceptible to theft and vandalism, again because of their high profile nature necessary to produce power. Solar and wind generating systems can be very expensive to purchase and do not guaranty a regular supply of energy. They are dependant upon favorable weather conditions, which can present enormous problems to mission critical systems that might depend on them for power.

What is needed then is a hydroelectric turbine generator system that is designed to extract a particular amount of energy from a fluid flowing under pressure yet is able to sustain most of or a majority of the inlet pressure downstream of the turbine device. Such a system would allow the production of electric power to implement important electronic components or other electrical equipment and still permit the continued operation of the fluid transfer system by sustaining its required operating pressure.

It is therefore, the purpose of this invention to provide a system that addresses the need for generating electric power using an inline turbine-generator system, which generally consists of a reaction type axial impeller, turbine housing and an electric generator device. This invention provides a hydroelectric turbine system that is able to generate a particular amount of electric power by converting energy from fluid flowing under pressure through a pipe, that subsequently drives the impeller connected to a shaft that turns a generator device that produces electricity, and systematically sustains a majority of the upstream inlet pressure downstream of the turbine housing's discharge end. Furthermore, and critical to this invention, is the expeditious manner in which fluid is conveyed through the system by maintaining as much flow velocity as possible.

Since the design objective of this invention is to produce enough energy to power, for example a control system, solenoid valves and/or an electrical storage means like batteries or capacitors that supply the system when generated power is not available. However, when supplying a charge to batteries, more is always better to assure the maximum amount is saved and stored. Creating a sufficient amount of voltage and current, or even more, does not require significant pressure or pressure loss to the hydraulic system due to the efficiency of the inventions turbine design. This turbine design can produce over ten amperes of power depending upon the generator or alternator device used in conjunction with the system and the impeller vane height and length, and is enough to supply a charge to a battery and an electronic system's requirement. Surplus hydraulic pressure is subsequently used so that very little, if any, is wasted.

DESCRIPTION OF THE INVENTION

The hydroelectric turbine generator system of this invention is called a small, mini, micro or pico type reaction turbine design and is capable of maintaining an amount equal to or less than fifty 50 percent of the dynamic pressure differential between said inlet and outlet sections.

Most small and large scale water or fluid flow delivery or transfer systems require certain amounts of hydraulic pressure to drive them or to push fluid from one location to another through a pipe system or pipe line network. Utilizing the kinetic energy from fluid flow under hydraulic pressure to power electronic systems or other electrical devices in remote areas is a logical way to promote the use of such important electronic monitoring, management and control systems. Remote facilities like fixed cellular sites, wireless repeater stations, weather or atmospheric sensors or even homes and commercial or industrial facilities could be powered if a pipe line that contains a fluid flowing under pressure were in near proximately and retrofitted with a small sized turbine as explained by this invention. Only a portion of the kinetic energy from fluid flowing under pressure would be utilized, by this invention, to power such devices, systems or facilities while still permitting a substantial amount of that energy to continue its mission of moving the same fluid from one place to another. The turbine system would be used to serve as a control means to slow the flow down to prevent damage from out of control pressures or hydraulic hammering and of course to produce electric energy.

Since the system produces low voltage and powers devices that are already designed to operate with low voltage, expensive electricians are not required for installation or maintenance. Additionally, there will be less liability exposure to landowners and contractors working with or maintaining the system since low voltage supply and equipment are generally viewed as being extremely safe.

U.S. Pat. No. 7,190,088 issued to Heidel, claims a hydroelectric turbine generating system design that can be utilized in pressurized main pipe lines, water tower pipe lines, sewage lines canals and aqueducts. The turbine design explained teaches a Pelton style impeller that is driven tangentially with the blade ends or cups on one side of the turbine being in contact with water flowing through a pipe; wherein, said flow drives the shaft that turns the generator. The design appears to make only limited contact by blade ends in water flow and does not appear capable of taking advantage of the full flow volume that would be contained in a typical system the patent describes. This design characteristic is very different to, and contraststhis invention's design. The turbine is as taught by this invention, incorporates a vaned impeller and not blades as explained in Heidel, and makes full contact with all fluid flowing through the pipe it is connected to. This constracts, the invention turbine, which is capable of efficiently producing more energy by utilizing all flow volume, and yet without robbing the hydraulic pipe line system or network of needed pressure to continue the movement of fluid to fulfill downstream pressure requirements.

The invention's turbine as explained herein could be implemented to power specific field devices such as a FX module found in the Techstream Control System's, Inc. XLinc wireless valve and sensor transceiver system U.S. Pat. No. 7,050,887. The FX or field transceiver module is hardwired to valves and sensors and wirelessly receives command signals from a CX module. As the FX module receives command signals from the controller and CX module to open or close valves. The XLinc's FX module is typically installed in a remote location and requires electric power to operate. Thus, the invention's turbine could be utilized to charge a battery that powers the FX module, or other devices like it, and its valves or sensors. Similarly, other electronic devices could be powered such as relays, switches or any other devices that require VAC or VDC electric power to operate. The invention's turbine system would be used to charge a battery or capacitor that provides power to those systems or can power an electronic device directly.

A Wireless Irrigation Control System is described in Dodds U.S. Pat. No. 5.333.785, and explains a system wherein the irrigation valves and associated decoder devices receive electric power from a plurality of power generating devices that are in connection with and adjacent to each valve. Dodds explains that the generating means are specifically located to power field valves and not the entire system as is claimed here by this invention's turbine system. In fact, the inventions turbine does not claim a particular system size or capacity relative to pipe attachment sizing, power output or application, but rather a system design that can be applied to any size system and placed at any location within that system. Therefore, the invention's turbine can be applied to an entire electronic system or more, and is not limited to powering its valves, radio receiver and decoder only as explained in Dodds. Furthermore, by way of comparison, Dodds claims “a plurality of power generating means corresponding to each of said control valves and being located adjacent thereto”, as explained in Dodd's claim 1, but does not claim the ability to power an entire electronic control system or recharge batteries that would be required to power an entire system. The Dodds power generating means is far more limited in its electrical output capacity; whereas, the TCS turbine is not so limited.

Motorola U.S. Pat. No. 4,838,310 explains a system, similar to Dodds that is limited to powering field valves and radio receiver devices and switch type mechanisms only and not an entire electronic control system wireless, wired or otherwise. The patent explains an irrigation system specifically and involves transmitting radio signals that actuate irrigation valves and a turbine power generating source that provides electricity to a battery that supply those valves and receiver module. Again, like Dodds, a specific control system is explained and even though reference is made to a turbine impeller generator means, it appears that it is only directed to function with the irrigation control system the patent claims. The “preferred battery” storage specification explained in Motorola calls for a NI-CAD battery and implies a smaller electronic system that targets a smaller power consuming device and not a complete electronic control system that incorporates multiple sensor inputs and communication equipment necessary to monitor and manage centrally from a remote office location, which the TCS turbine is designed to do. One versed in the art will recognize that a NI-CAD battery is typically used in smaller electronic devices and are not efficient or practical for use as a major large scale electrical storage alternative such as high amperes lead-acid batteries.

The physical appearance of the Francis turbine might appear closest of all existing hydro turbine designs to this invention because of its distinctive volute or scrolled shaped housing. However, the similarity is purely aesthetic as both operate in literally different directions. Though both require sealed impeller chamber housings so as to achieve maximum performance, every other aspect is entirely different and serve to function contrasting purposes.

There are at least three significant points that differentiate the Francis from this invention's design concept. First, the designs operate in opposite flow directions relative to their volute housings. Two, the inlet and discharge size dimensions are opposite. That is, the inlet is typically larger than the outlet on the Francis, contrasting the smaller inlet than the outlet that is characteristic of this invention. And finally, and most significant, the impeller designs are very different and neither would work in the other's turbine housing to achieve the same results. The Francis is in an inward flow design; whereas, this invention teaches an axi-radial flow type disk design that directs flow outwardly from the center rather than tangentially and then in on its self like the Francis.

This invention's turbine incorporates a scrolled discharge section to efficiently manage and release flow as it exits the impeller to sustain velocity; whereas, the Francis uses the scroll to manage inlet flow and directs it around the first runner vanes on its impeller. The two designs operate in opposite directions. That is, fluid flow enters the Francis turbine's inlet scroll portion of the housing first, and then second, contacts the impeller tangentially within the impeller chamber, and then third, immediately exits the system from the impeller's second vane runner. The invention's design, by contrast, takes flow straight into the impeller first, in an axial radial direction, and then releases it into the discharge scroll, and second, then out the outlet end where it is directed back into the fluid flow pipe line. The Francis simply drops the fluid flow out of the impeller's second vane runner and is typically unconcerned with it after that point; whereas, this invention's turbine organizes the flow after it leaves the impeller and seeks to preserve its momentum thereby sustaining it's kinetic energy.

Bringing the flow back to the center and on itself, as the Francis does, reduces flow velocity and contributes to restriction and would be inefficient relative to the invention's stated design objective.

The Francis design seeks to modify incoming flow by increasing head pressure head before hitting the first runner of vanes at maximum velocity. This inventions impeller, on the other hand, is of an outward flow design and seeks to sustain flow velocity by first contacting the face's spinner as hydrodynamically as possible in an axial direction to the center, and then directing it out radially over the curved face from the center. The inventions turbine utilizes the volute shaped scroll to convey fluid away from the impeller, where as, the Francis uses the scroll to direct it into the impeller.

DESCRIPTION OF THE PREFERRED EMBODIMENT

The turbine design requires that fluid flowing through the system, as herein described, encounters few, if any, hard or flat angle surfaces, straight or flat angle positive or negative corners or edges once it has entered the system. The hydrodynamic design requires that fluid flowing through the system encounter only sloping curved and rounded or radiused surfaces, rounded or radiused corners and edges and round bulbous ends or points, with the only exceptions being knifed straight edges where fluid flow makes first and last contact with a surface. This hydrodynamic design theme applies to all internal components that come into direct contact with fluid flow.

Turns in pipe direction leading into and out of the inlet and outlet sections of the inventions turbine ideally follow the same or similar sweeping curved designs contained within the turbine for the purpose of minimizing hydraulic restriction and pressure loss. Swept pipe sections or flexible hose can be utilized and can be made of a variety of materials including rubbers, poly materials, plastic materials, composites, iron, steel, alloys or any other material.

A by-pass valve can be any type of manual or automatic valve that can be adjusted to open or close, or any position in between. A manual valve such as a gate or ball valve could be adjusted and set at a variety of positions to enable more or less performance by the turbine. An automatic valve such as a solenoid hydraulic valve is utilized to restrict pipe line flow by setting the opening height of its internal flow control mechanism or by completely closing the device when full turbine performance is needed. A by-pass control valve option can also include actuation type valves or valves that are incrementally adjusted by a servo motor or an actuator. Such valve systems can be used to more precisely control the amount of flow that alternatively passes through the by-pass or through the main pipe line. Multiple by-pass lines can be incorporated to further contribute to more precise flow and pressure regulation.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

FIG. 1 shows the frontal and rear projections of the turbine unit housing 1. The back view shows the volute scroll like shape of the housing 8 and the back plate 11 which is attached to the back of housing 1 b using attachments 17 appropriate for the pressures that are to be expected during use of the invention. The center of the backing plate 11 shows ingress 11 i for a shaft 10 which is shared in common and connected to impeller 4 and power generating means 33 to produce electrical energy. The frontal view shows fluid flow ingress port 2, through which incoming flow under pressure 21 enters, port 2 having a diameter 2 d, and discharge portal 3, which allows for the egress of fluid from housing 1. Ingress port 2 is centered about the vertical axis of housing 1. Fluid flow under pressure 21, exiting from discharge port 3, is noted to be mostly perpendicular from the fluid flow 21 at fluid ingress port 2. An embodiment to this invention, not shown, is the ability to route the flow of fluid exiting from discharge port 3 to be in a direction axially related to the incoming flow 21. Hydraulic pressure pushed or drives the fluid into via ingress pipe 27 e and out of the system through egress line 31 as shown in FIG. 8. Fluid discharge volute 8, circumferentially surrounds housing 1 along the horizontal axis, increases in volumetric size obtaining maximum diameter 8 m approximately 360 degrees from the beginning of volute 8 at approximately 90 degrees below ingress port 2, where volute 8 has it's minimum volumetric size at 8 s. Volumetric size of the interior portion of volute 8 increases as a ratio of the cumulative volumetric openings of the impeller are exposed to the interior of volute 8. The volumetric size of volute 8 will never be smaller than the cumulative volumetric size of all of the openings of the impeller so as to decrease pressure loss and turbulence. FIG. 4 shows that volute 8 has an interior surface 8 i and an exterior surface 8 e. Interior surface 8 i forms an arc whose opening is aligned with the horizontal axis of housing 1. Housing structural brace 1 f provides support to exterior surface 8 e where the discharge portal 3 joins volute 8, providing thrust support during startup. Not shown is the ability to attach utility ports along housing 1 so that instruments, pressure gauges or sensors can be attached to housing 1. The turbine housing assembly 1 consists of a body and components that can be constructed of numerous materials including rubbers, poly materials, plastic materials, composites, iron, steel, alloys or any other material.

FIG. 2 shows the addition of a power generating means along with coupling plate 34. Plate 34 interfaces with backing plate 11 facilitating the bolt pattern of a power generating means. Plate 34 will have varying configurations to adapt to the different power generating means available to interface with this invention. FIG. 2 show an alternator type of power generating means whereby alternator 33 has shaft 10 and a bolt pattern that will interface with plate 34 and backing plate 11. In this embodiment, the power generating means is in axial alignment with the center of rotation of impeller 4 along vertical axis of housing 1. Not shown are other embodiments where the power generating means are attached to shaft 10 through means of gears, pulleys or other power transmission means, allowing for multiple power generating means to be associated with a single housing or where space limitations dictate a more compact style for a single power generating means.

FIG. 3 is an exploded view of the interface between the power generating means 33, coupling plate 34, backing plate assembly 11, impeller 4 and housing 1 in a cross-sectional view. The front of housing 1 fr is the first object in the assembly. Fluid flow 21 enters ingress port 2, centered about the vertical axis of housing 1, and is adapted to receive fluid flow under pressure 21 from any range of piping systems through a coupling means 2 t and comes in contact with spinner 20. In this invention, threads are the coupling means. The impeller chamber 7 is immediately adjacent to and is in fluid flow communication with, ingress port 2, and is shaped to conform to the exterior contour of impeller 4. It is critical that there is a minimal amount of clearance between the housing's interior slope 7 s and the back plate 11 and impeller 4 so as not to interfere with the rotational functioning of impeller 4 under the force of fluid present. FIG. 3 details the change in diameter 8 d from the upper portion of the housing 1 to the lower discharge port 3. Discharge channel 9, which is circumferentially in communication with interior of volute 8 i, facilitates the fluid communication between fluids expelled from impeller 4 and is shaped to be slightly larger than the height of vanes 18 at the discharge location 18 dh. Fluid exits impeller discharge end 5, then swirls out through the discharge channel 9 and into the directionally shaped internal volute 8 i that is in fluid communication with circumferential outer edge of the impeller discharge end portion 5. Discharge channel 9 dimensional characteristics pertaining to the measurement of it's height and width, can be varied to a limited extent to accommodate different impeller sizes without having to replace the entire housing 1. The inner diameter of the volute 8 i can become larger as the fluid makes its way through the scroll and into the discharge or outlet end 3, in one embodiment of the system. The impeller 4 turns rotationally 24 in the opposite direction to the flow 21. As the fluid leaves said housing discharge outlet section 3, it rejoins down stream portion of said pressurized hydraulic pipe line 16, which is connected to the turbine housing 1, and is subsequently conveyed wherever the pipe line and its end openings distributes it, as shown in FIG. 8.

Housing back 1 b is adapted to accept housing back plate 11 thereonto using appropriate connection means for the pressures anticipated. This invention uses bolts which are threadably attached to mountings 1bt. Plate 11 is further sealed from leakage by O-ring 12. The impeller back face 25 side is located adjacent to the housing back plate 11, which is the part that seals the impeller within the housing 1. The back plate 11 also serves as the mounting surface 17 for the electrical generator device not shown selected to function with the turbine system. The back plate seals against the housing using an O-ring 12. A vane height spacer 22 can be utilized to center the impeller 4 within the impeller chamber 7 and is located between the back face 25 and the back plate 11. The vane height spacer 22 is used when narrower lower flow impellers 4 are incorporated wherein the spacer 22 occupies the void area within the chamber 7 to minimize the gap between the back face 25 and the back plate 11. The impeller shaft 10 passes through the center of the back plate 11, the vane spacer 22 and threads into the back face 25 side of the impeller face 15. A mechanical seal 13 can be utilized on the shaft 10 and between the impeller face 15 and the back plate 11 to seal the housing's internal pressure from external atmospheric pressure.

Unlike prior art designs, the sloped or curved natured of the face allows fluid flow 21 to contact the impeller 4 without loosing significant velocity. A hydrodynamic spinner 20 is placed at the leading point of the impeller and enables the expeditious transition of flow 21 from the by-pass ingress line 27 directly into the impeller 4. Ingress line 27 is coupled to turbine 26 through coupling means 32. Flow is received directly from the pipe line 16 and into the shrouded 14 impeller inlet 6 and, once having crossed the spinner 20, enters the sloping curve of the impeller face 19, which serves as the drive section of the impeller as hydraulic pressure is built-up and pushes against the logarithmic spiral designed vanes 18 that are radially and strategically located upon impeller front face 23. A shroud cover 14 can be optionally placed over the hydraulic drive side or front face side of the impeller.

Each prospective installation location will require the system operate with under various flow rates, static and dynamic pressures, pipe size inner diameters and power production requirements. The turbine is therefore designed to be able to adjust to these conditions by, generally, offering differing impeller 4 size diameters that include varying vane height 18 hl, height, length and curves so as to maximize the efficiency of the system operating in a variety of conditions. Vane height and length variations contribute to the regulation of flow 16, flow restriction, shaft 10 rotational velocity or speed, rotational torque energy and subsequently power production. Taller vanes 18 permit more flow 16 volume and less flow restriction, but can reduce power production by decreasing shaft 10 speed, while shorter vanes are more restrictive and reduce flow, but increase power production by increasing shaft 10 rotation turn speed. Similarly, vane length 18 hl and subsequent impeller diameter affects shaft 10 rotation speed and torque. Shorter vane lengths provide higher turn speed but with less kinetic energy or torque, while longer vanes provide lower turn speeds but with more torque or rotational power. Vane length selection will be important when selecting a particular electric generator 33 device to operate with this invention and will be most critical when functioning with a less efficient unit. An efficient generator 33 will produce more energy at a lower shaft 10 turn speed and will require less torque to achieve it, while an inefficient generator will require higher shaft 10 turn speed with greater torque. Determining the correct selection of an impeller for a particular site or location should involve consideration of flow restriction, shaft 10 rotation speed, shaft spin torque characteristics and power production requirements.

Similar to the vanes, the shape and size of the spinner 20 will vary depending upon performance requirements of the system. Lengthening and narrowing its diameter will allow more flow 21 to pass into the impeller inlet 6, while shortening and making it thicker or larger in diameter will create increased head pressure. The latter will contribute to higher spin or shaft 10 turn speed and subsequently more electrical energy, but will increase pressure differential between the housing inlet 2 and outlet 3. The former conversely, will reduce the impeller shaft's 10 speed or turn velocity with decreased power production, but will also decrease the pressure differential between the inlet 2 and outlet 3 sections. In either case, the leading end of the spinner or the portion that makes first contact with flow 21 from the fluid flow source 16 will encompass a hydrodynamic curved or rounded bulbous point. Stator vanes not shown that further assist in directing flow and contribute to increasing shaft 10 turn speed, can be incorporated into the curved impeller face 19 or may also be incorporated just behind the spinner's 20 rounded leading end.

Referring now to FIG. 8, a by-pass pipe ingress line 27 emanating from main pipe 16 and by-pass egress line 31 which discharges back into main pipe 16 creates the by-pass piping structure which enables the turbine system 26 to utilize either all or only a portion of the pressure and flow 21 that is available in a larger pipe main line 16. Pressure and flow to the by-pass line would be adjusted or regulated by increasing or decreasing flow by restricting it between the upstream location where the by-pass branches off the main line to the ingress pipe 27 and the downstream side where the by-pass pipe reenters or reconnects to the main line on the egress pipe 31 side. Restricting the flow in the main pipe line 16 to increase or decrease flow to the by-pass piping structure is accomplished by the use of a by-pass flow control valve 28. A flow control valve 28 can be placed in the main line 16, being coupled by coupling means 32, between the locations where the by-pass pipe line first connects to the main line 27 and again where it reenters the main pipe 16 through discharge pipe 31. Turbine system 26 will provide current for application use or to be stored by battery 33 shown encased by housing 30.

Opening the by-pass flow control valve 28 would permit full flow 21 through the main pipe line 16 thus diverting it from the by-pass line 27 and the turbine system 26. Power would not be produced as all flow energy is directed away from the turbine 26. If more flow or pressure were required to drive, for example, irrigation valves and high flow sprinkler heads, the irrigation control system would be programmed to open the by-pass control valve 28 to increase dynamic flow or downstream flow 21 and pressure. This would reduce flow to the turbine system 26 and subsequently limit power production, but would permit the additional dispersion of water to the larger irrigation coverage zone that requires it. Conversely, closing or limiting flow 21 through the by-pass control valve 28 diverts fluid flow 21 from the main line 16 and redirects to the ingress pipe 27 and into the turbine system 26. Increased flow and pressure diverted into the by-pass line and turbine would increase power production by the pressure differential that would be created by the valve's closing action. Pressure differential would occur between the ingress pipe 27 and egress pipe 31 where it reenters the pressurized hydraulic pipe line 16 which can be measured through pressure gauge 29.

The turbine system design is specific to the impeller and turbine housing and can function with, or can be adapted to, most any electrical generator or alternator unit device produced by any manufacturer. The design, as herein explained, is intended to be flexible and adaptable, and able to adjust to the demands that are unique to the different types of applications and varying site conditions that may exist.
